If you’re considering buying a new rock drill for your project or company, there are a number of things to take into consideration before taking the plunge. Rock and mining site conditions, budgets, anticipated future projects, noise, desired hole dimensions, existing equipment and available time are all factors that you should take into account before making that purchase. We’re going to outline some of the major differences between top hammer, or drifter drills, and down-the-hole, in-the-hole, or DTH drills.

Bulldozers (or dozers) are crawlers equipped with blades made of substantial metal.

At the rear, dozers are equipped with rippers (claw-like devices) for loosening compacted soil and rocks.
